I did not give up! And I did everything I read above, in the help and something else.
– Update all USB 3.0 drivers on my PC and the same error appeared.
– Reinstall the software and get the same error.
– Connect the Tobii and restart the PC with the Tobii connected and the same error came out.
– Plug in and unplug once, again and again the Tobii from the PC and backwards … and connected!
I am happy ! =D
PS: I think it did not connect because as the cable is new, it must have some material on the pins and that when connecting and disconnecting again and again, this material was removed. Something similar to the pins of agunos microcontrollers.
